U.S. refiners forecast strong first-quarter earnings as margins on gasoline and diesel sales improved, refining capacity fell sharply and crude supplies tightened due to the Russia-Ukraine war.
Global refining capacity has declined amid the coronavirus pandemic, with several less profitable refineries closing in the past two years. However, global fuel demand has rebounded to near pre-pandemic levels, boosting the profits of facilities still operating.
Seven U.S. independent refiners are expected to earn 61 cents a share, compared with a loss of $1.32 in the first quarter of 2021, according to Refinitiv's IBES.
By 2022, gasoline and distillate foamed concrete.
1. Determine the material
The compatibility of cement foaming agents and the foaming machine is the first consideration. Because there is a problem with compatibility between cement foaming agent and cement foaming machine. To understand the compatibility of the cement foaming agent, it is also necessary to determine the reasonable dilution ratio of the foaming agent. If it is the first time using the cement foaming agent, it is recommended to refer to the dilution ratio recommended by the manufacturer and then combine it with your machine test to find the most suitable dilution ratio.
2. Cleaning up the construction site
The first is to clean up the debris and install the water and electricity. Sprinkle cleaning to moisten the surface of the cast-in-place operation; pay attention to the watering must be even and do not have water accumulation.
3. Test whether the foam generator is regular in advance
The test method is to dilute the foaming agent according to a specific ratio, then make foam, and arrange the foam outside the machine to see whether the foam moisture content and the viscosity of the foam are standard.
Whether the bubble is about 1mm, if the moisture content is high, the cells may need to be replaced with steel balls.
4. During the construction of foamed concrete, it should be noted that the slurry of foamed concrete cannot stay, and it should be leveled immediately after pouring to make it stop.
To prevent the foam from breaking and collapsing after re-construction after static stop.
5. Attention should be paid to the influence of air temperature during the construction of foamed concrete. When the air temperature is below 10 degrees, a foaming agent with high stability and suitable for winter application should be selected.
When the air temperature is lower than 5 degrees, it is recommended to use early-strength composite Portland cement in addition to an excellent foaming agent. If conditions permit, a simple plastic greenhouse can be built.
6. Construction in summer requires main moisturizing and maintenance. There are two ways to choose, one is to cover straw curtains, reed mats, sacks, sawdust, wet soil, and wet sand, and the other is to cover with plastic sheets

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the foamed concrete, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the foamed concrete chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.
The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment. For more information about foamed concrete, please feel free to contact us.
